Orange and white are colors traditionally associated with the Signal Corps. The shield is divided into two parts to represent the dual functions of the unit, supply and maintenance. The hand grasping the flash symbolizes the mission of the unit. The flames denote the zeal and readiness of the organization to carry out its mission. The four wavy barrulets refer to the four places of the unit's activation--Italy, Germany, Japan and the United States. The wavy barrulets allude to the Arno River, the area in which the unit earned a battle honor for services during World War II.
The lightning flash, a symbol of the Signal mission, represents the unit's World War II campaign in Italy. The mural crown further recalls European service during the war. The flames symbolize signal fires used in the past and refer also to the worldwide conflict during which the unit saw distinguished service. The flash denotes speedy response and is blue, alluding to modern electronics and telecommunications. Red stands for courage, yellow (gold) for excellence, black for stability and strength.
